Fixed a bug with the Reflects Damage monster affix that caused it to generate errors and deal no damage when triggered by a pet

Fixed a crash that could occur when Arcane Enchanted monsters spawned their arcane beams in locations outside of the game world

Fixed a crash that could occur when "uber" Skeleton King (in the Realm of Discord) or "uber" Rakanoth (in the Realm of Chaos) teleported outside of the game world

Fixed a crash that could occur when "uber" Siege Breaker (in the Realm of Turmoil) used his Roar attack while holding a player in mid-air
